DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

Embodiments of the present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all, embodiments of the invention are shown. Indeed, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to elements throughout. Where possible, any terms expressed in the singular form herein are meant to also include the plural form and vice versa, unless explicitly stated otherwise. Also, as used herein, the term “a” and/or “an” shall mean “one or more,” even though the phrase “one or more” is also used herein.

“Entity” as used herein may refer to an individual or an organization that owns and/or operates an online system of networked computing devices, systems, and/or peripheral devices on which the system described herein is implemented. The entity may be a business organization, a non-profit organization, a government organization, and the like, which may routinely use various types of applications within its enterprise environment to accomplish its organizational objectives.

“Entity system” as used herein may refer to the computing systems, devices, software, applications, communications hardware, and/or other resources used by the entity to perform the functions as described herein. Accordingly, the entity system may comprise desktop computers, laptop computers, servers, Internet-of-Things (“IoT”) devices, networked terminals, mobile smartphones, smart devices (e.g., smart watches), network connections, and/or other types of computing systems or devices and/or peripherals along with their associated applications.

“Computing system” or “computing device” as used herein may refer to a networked computing device within the entity system. The computing system may include a processor, a non-transitory storage medium, a communications device, and a display. The computing system may be configured to support user logins and inputs from any combination of similar or disparate devices. Accordingly, the computing system may be a portable electronic device such as a smartphone, tablet, single board computer, smart device, or laptop. In other embodiments, the computing system may be a stationary unit such as a personal desktop computer, networked terminal, IoT device, or the like.

“User” as used herein may refer to an individual who may interact with the entity system to access the functions therein. Accordingly, the user may be an agent, employee, associate, contractor, or other authorized party who may access, use, administrate, maintain, and/or manage the computing systems within the entity system. In other embodiments, the user may be a client or customer of the entity.

Accordingly, the term “user device” or “mobile device” may refer to mobile phones, personal computing devices, tablet computers, wearable devices, and/or any stationary or portable electronic device capable of receiving and/or storing data therein.

“Data transformation algorithm” as used herein may refer to a set of logical and/or mathematical operations or processes that may be executed on a specified segment of data to produce a transformation output. Accordingly, in some embodiments, the data transformation algorithm may be a cryptographic hash function or hash algorithm (e.g., MD5, Secure Hash Algorithm/SHA, or the like) which, given a specified data input, produces a cryptographic hash output value (e.g., a fixed-length character string).

“Virtual environment” as used herein may refer to a computing environment that may be physically and/or logically isolated from other environments and/or computing systems within the network. “Virtual environment instance” as used herein may refer to a particular configuration of a virtual environment that may be created for a given time period. Each virtual environment instance may have separately allocated resources, processes, system files, drivers, and applications. Accordingly, processes or code that may be executed within a virtual environment instance will only affect the state of the virtual environment instance.

“Malware” as defined herein may refer to executable code which may cause the execution of one or more unwanted or unauthorized processes on a target computing system (e.g., deleting or corrupting files, modifying data, encrypting files, or the like). Accordingly, malware may include viruses, worms, spyware, adware, or the like.

“Logic bomb” as used herein may refer to a specific type of malware that may execute unwanted or unauthorized processes upon detecting the occurrence of certain specific conditions. Examples of such conditions may include the occurrence of a particular date, the passage of a designated amount of time, execution of certain operations, or the like.

Executable code that causes execution of unauthorized processes may cause and/or creates unintentional consequents may create significant operational impacts on the computing systems within a network environment. Accordingly, an entity may wish to perform validation and security testing of executable code (e.g., software applications, updates and patches, or the like) before the code is permitted to be executed and/or installed onto any of the entity's computing systems. In this regard, an entity's system may generate a virtual environment instance in which executable code may be tested and validated for execution and/or installation. Once the executable code to be tested may be opened within the virtual environment, the system may execute a set of operations or commands with respect to the executable code (e.g., installing the application, using certain functions or features of the application, performing system processes, installing software updates, and the like).

The system may generate a log of all actions performed within the virtual environment along with the outcomes associated with the actions performed. For instance, such outcomes may include the discovery of malware, software incompatibilities, driver faults, operating system errors, application bugs and/or instability, or the like. If the system detects that executing the set of operations on the executable code has not caused any detrimental outcomes to appear, the system may validate the executable code (e.g., determine that the executable code is safe to execute). In some embodiments, validating the executable code may be conditional on certain factors (e.g., the executable code is validated only with respect to certain computing systems having a particular software and/or hardware configuration). Once the executable code is validated, the system may input the executable code into a data transformation algorithm to produce a data output. For instance, the data transformation algorithm may be a hash algorithm such as SHA such that a hash output is generated from the executable code. The hash output associated with the executable code may then be stored in an authorized/validated hash database.

Once the validated hash database is generated, new sets of executable code may be hashed to produce new hash outputs. If the new hash output matches a hash stored within the validated hash database, the system may recognize the executable code as validated and thus authorize the installation and/or execution of the executable code. If no match is detected, the system may require that the new executable code is evaluated within the virtual environment before it is permitted to be installed or executed. In some embodiments, the system may further comprise an unauthorized hash database comprising a list of executable code that the system has determined to produce undesirable effects in computing systems (e.g., the executable code contains malware, causes instability or crashes, or the like). In such embodiments, if the hash of a particular set of executable code matches a hash found within the unauthorized hash database, the system may automatically block the installation and/or execution of the set of executable code. In this way, the system may provide a secure way to perform validation testing of executable code that may reveal issues that may not be detectable based on a line-by-line analysis of the code.

In some embodiments, the system may only allow validated executable code to be installed and/or executed on certain designated computing systems. For example, certain executable code may only be validated to run on computing systems having specific hardware and/or software configurations (e.g., to avoid unforeseen compatibility issues). In such embodiments, the system may generate hash outputs of the environment (e.g., computing system) in which the validated executable code is to be installed and/or executed (referred to herein as “environment hashes”). The environment hash may be generated using specified core information about such computing systems (e.g., operating system platform and version, installed software, processor architecture, or the like). The environment hash may then be stored within the validated hash database (or within an environment hash database).

Subsequently, before installing or executing a particular set of executable code, computing systems may be required to not only generate a hash of the executable code for validation checking against the values within the validated hash database, but may further be required to generate an environment hash based on currently detected environment hash variables for validation checking against the values within the environment hash database. If a mismatch is detected in the hash values of the executable code or of the environment (e.g., the computing system has experienced a core hardware or software change), the system may prevent the execution of the executable code until the mismatch is remediated (e.g., the executable code and/or environment are re-validated and their respective hashes are updated within the hash database).

An exemplary embodiment is provided as follows for illustrative purposes. In one embodiment, an employee or third party contractor of an entity may be tasked with deploying a software update on the computing systems within an onsite network. The software update may be stored, for instance, on a portable flash memory drive held by the employee. In such an embodiment, the system may comprise a designated computing system (e.g., a kiosk) which may be dedicated to running the virtual environment in which executable code is to be tested. In another embodiment, the virtual environment may be implemented on a portable drive which may be connected to another computing system to generate instances of the virtual environment on the computing system (e.g., the computing system to receive the update).

The employee may access the software update through the virtual environment (e.g., by connecting the portable drive containing the update to the kiosk). In some embodiments, the employee may select a predetermined set of operations to be executed with respect to the software update (e.g., installation, troubleshooting, or the like). In this regard, the virtual environment may display a user interface of the operating system on which the update is to be installed. In this regard, the virtual environment may simulate the exact hardware and/or software configuration of the computing systems on which the software update is to be deployed. In this way, the employee may go through a process of installing the update within the virtual environment that is identical to the process of installing the update on the target computing systems. In other embodiments, the system may automatically execute the predetermined set of operations based on the identity of the executable code to be tested, which may be determined according to file extensions, metadata, or the like. In such embodiments, the system may automatically detect the occurrence of any unauthorized or undetected activity during the testing process.

If such activity is detected by the system, the kiosk may provide feedback to the user indicating the presence of such activity. For instance, a display (e.g., a monitor, projector, or the like) of the kiosk may display an indication that the executable code is not safe to run (e.g., a red screen or a “NO GO” message). In response, the employee may recognize that the update is not to be installed on any of the computing systems on site. On the other hand, if no undesirable activity is detected during testing or if the hash of the software update matches a hash within the validated hash database, the kiosk may display an indication that the executable code is safe to run (e.g., a green screen or a “GO” message). In such scenarios, the employee may be confident that the software update may be deployed without incident. Upon completion of the validation process, the system may generate a hash of the tested code and store the hash within the validated hash database (or unauthorized hash database in some embodiments).

The system as described herein confers a number of technological advantages over validation systems. For instance, by using a virtual environment, the system may provide a secure, isolated way of performing validation and safety testing of executable code before it is deployed on target computing systems (e.g., computers within a production environment). Furthermore, maintaining a database of validated hashes (or unauthorized hashes) may allow an entity to maintain precise version control with respect to software that may be installed on its computing systems.

Turning now to the figures, FIG. 1 illustrates an operating environment 100 for a secure virtual environment system, in accordance with one embodiment of the present disclosure. In particular, FIG. 1 illustrates a secure virtual environment device 106 that is operatively coupled, via a network, to a target computing system 103 and a hash database system 104. In such a configuration, the secure virtual environment device 106 may, in some embodiments, transmit information to and/or receive information from the target computing system 103 and/or the hash database system 104. It should be understood that FIG. 1 illustrates only an exemplary embodiment of the operating environment 100, and it will be appreciated that one or more functions of the systems, devices, or servers as depicted in FIG. 1 may be combined into a single system, device, or server. For instance, the functions of the secure virtual environment device 106 and the hash database system 104 may be performed by a single computing system. Furthermore, a single system, device, or server as depicted in FIG. 1 may represent multiple systems, devices, or servers. For instance, though the target computing system 103 is depicted as a single unit, the operating environment may comprise multiple target computing systems.

The network may be a system specific distributive network receiving and distributing specific network feeds and identifying specific network associated triggers. The network may include one or more cellular radio towers, antennae, cell sites, base stations, telephone networks, cloud networks, radio access networks (RAN), WiFi networks, or the like.

Control and signal processing functions of the system are allocated between these processing devices according to their respective capabilities. The processing device may include functionality to operate one or more software programs based on computer-readable instructions thereof, which may be stored in a memory device.

The processing device 154 may be operatively coupled to the communication device 152 and the memory device 156 such that the processing device 154 uses the communication device 152 to communicate with the network and other devices on the network, such as, but not limited to the target computing system 103 and the hash database system 104. In this regard, the communication device 152 generally comprises a modem, antennae, WiFi or Ethernet adapter, radio transceiver, or other device for communicating with other devices on the network.

Accordingly, the target computing system 103 may be a device such as a desktop computer, laptop, IoT device, smartphone, tablet, single-board computer, or the like. The target computing system 103 may comprise a user interface comprising one or more input devices (e.g., a keyboard, keypad, microphone, mouse, tracking device, biometric readers, capacitive sensors, or the like) and/or output devices (e.g., a display such as a monitor, projector, headset, touchscreen, and/or auditory output devices such as speakers, headphones, or the like).

The target computing system 103 may comprise a processing device 134 operatively coupled to a communication device 132 and a memory device 136 having data storage 138 and computer readable instructions 140 stored thereon.

A hash database 182 (which may be referred to herein as an “authorization database”) may be stored within the data storage 178 of the hash database system 104, where the hash database 182 contains the hashes of executable code that has been tested. In some embodiments, the hash database 182 may be a validated or authorized hash database which stores hashes of executable code that has been validated (e.g., code that has been determined by the system to be safe to install and/or run). In other embodiments, the hash database 182 may be (or further include) an unauthorized hash database which stores hashes of executable code that is unauthorized (e.g., code that has been determined to produce undesirable effects) to be installed or executed on computing systems within the operating environment 100 (e.g., the target computing system 103). In embodiments in which the validated hashes are tied to certain computing systems, the hash database 182 may further comprise environment hashes of computing systems which have been approved to install and/or execute the executable code as defined by the system.

In this way, the computing systems may transmit and receive web content, such as, for example, product valuation, service agreements, location-based content, and/or other web page content, according to a Wireless Application Protocol (WAP), Hypertext Transfer Protocol (HTTP), and/or the like.

A processing device may also be capable of operating applications. The applications may be downloaded from a server and stored in the memory device of the computing systems. Alternatively, the applications may be pre-installed and stored in a memory in a chip.

The chip may include the necessary circuitry to provide integration within the devices depicted herein. Generally, the chip will include data storage which may include data associated with the service that the computing systems may be communicably associated therewith. The chip and/or data storage may be an integrated circuit, a microprocessor, a system-on-a-chip, a microcontroller, or the like. In this way, the chip may include data storage. Of note, it will be apparent to those skilled in the art that the chip functionality may be incorporated within other elements in the devices. For instance, the functionality of the chip may be incorporated within the memory device and/or the processing device. In a particular embodiment, the functionality of the chip is incorporated in an element within the devices.

The devices may further include a power source. Generally, the power source is a device that supplies electrical energy to an electrical load. In some embodiment, power source may convert a form of energy such as solar energy, chemical energy, mechanical energy, or the like to electrical energy. Generally, the power source may be a battery, such as a lithium battery, a nickel-metal hydride battery, or the like, that is used for powering various circuits, e.g., the transceiver circuit, and other devices that are used to operate the devices. Alternatively, the power source may be a power adapter that can connect a power supply from a power outlet to the devices. In such embodiments, a power adapter may be classified as a power source “in” the devices.

FIG. 2 illustrates a process flow 200 for performing an initial validation of executable code using the secure virtual environment system, in accordance with some embodiments of the present disclosure. The process 200 begins at block 201, where the system imports a set of executable code into a virtual environment instance. The set of executable code may be automatically imported by the system, for instance, when a computing system within the network environment attempts to execute or install the set of executable code. In other embodiments, the set of executable code may be manually imported into the virtual environment by a user. For instance, in an exemplary embodiment, a user such as an employee of an entity may be tasked with installing a certain application on a number of computing systems within the entity's network environment. The user may be in control of a copy of the set of executable code which may be stored on a portable drive or, in other embodiments, a network drive. The user may load the set of executable code onto a dedicated validation kiosk configured to generate instances of the virtual environment. In other embodiments, the virtual environment software may be included on the portable drive such that virtual environment instances are generated using the computing systems on which the application is to be executed and/or installed (which may be referred to herein as “target computing system”).

The system may generate one instance of the virtual environment for each set of executable code to be validated. Each instance of the virtual environment may simulate the hardware, software, operating system, drivers, libraries, and the like of target computing system. The virtual environment may further be separated physically and/or logically from the target computing system. In this way, the system allows for the secure containment of the set of executable code such that the executable code may be evaluated without impacting the target computing systems.

The process continues to block 202, where the system executes, within the virtual environment instance, one or more processes on the set of executable code. The one or more processes may be executed based on the characteristics of the executable code (e.g., the executable code is used in the manner in which the executable code is intended to be used). For instance, if the executable code is an application, the one or more processes may include interacting with the application and/or using certain functions of the application (e.g., interacting with UI elements, calling functions, or the like). In another embodiment, if the executable code is an installation file (e.g., an application setup file), the one or more processes may comprise performing installation using the installation file. In some embodiments, the one or more processes may include scanning the executable code using anti-malware software. By executing the one or more processes, the system may detect latent issues or defects that may occur within the computing systems on which the executable code is executed or installed. For instance, the system may be able to detect the existence of malware, software/hardware incompatibilities, application and/or system instability, latency issues, or the like.

In some embodiments, the system may use time-accelerated execution of the one or more processes. During the time-accelerated execution, the system may execute all of the processes (including background system processes, malware scanning, interactions with and/or installation of the executable code, and the like) according to an accelerated time scale which may be faster than real time. For example, the system may run, in one minute of accelerated time, all of the processes that a computing system would normally run within one real-time day. By using time-accelerated process execution, the system may be able to expediently and efficiently detect issues that may arise over the passage of time (e.g., logic bombs, date/time issues, incompatibilities, or the like) that may not be immediately evident on a short timeline.

The process continues to block 203, where the system, based on executing the one or more processes, performs validation of the set of executable code. The system may maintain a log of all actions taken while executing the one or more processes on the set of executable code. Accordingly, the system may perform validation of the executable code based on the actions taken within the virtual environment instance. In some embodiments, the system may detect no issues with the executable code after executing the one or more processes. In such embodiments, validating the executable code may comprise determining that the executable code is safe to install and/or execute.

In some embodiments, the system may be configured to display a positive indicator on a graphical user interface which represents the system's finding that the executable code is safe and authorized to be installed/executed on the target computing system. For example, in embodiments in which the virtual environment is hosted on a dedicated kiosk, the display device (e.g., monitor, screen, projector, or the like) may display the positive indicator (e.g., affirmative text such as “safe” or “go,” a green background, or the like) to notify the user that the executable code may be safely installed and/or executed on the target computing systems.

In other embodiments, the system may detect one or more issues arising from the actions performed on the executable code within the virtual environment. In such embodiments, validating the executable code may comprise determining that the executable code is not safe to install and/or execute. Accordingly, the system may display a negative indicator (e.g., negative text such as “unsafe” or “no go,” a red background, or the like) on the display device to indicate to the user that the executable code is not authorized to be installed and/or executed on the target computing systems. In this way, the user may be able to tell at a glance whether a given set of executable code is authorized to be executed or installed on the target computing systems. Once the executable code has been evaluated, the system may delete the virtual environment instance.

The process continues to block 204, where the system processes the set of executable code using a data transformation algorithm to generate a data transformation output.

Once the executable code has been validated, the system may use the data transformation algorithm to generate a data transformation output which is uniquely associated with the executable code. In some embodiments, the data transformation algorithm may be a cryptographic hash algorithm (e.g., SHA, MD5, or the like) which may be used to generate a hash output which may reflect the exact state of the executable code as it was evaluated. Even a 1-bit deviation from the state of the executable code may result in a different hash output. Accordingly, once the hash output associated with a particular set of executable code is generated, the hash output may be subsequently used for validation of other instances of executable code encountered by the system.

The process concludes at block 205, where the system stores the data transformation output in an authorization database. In some embodiments, the authorization database may be an authorized hash database which may comprise hash values of all of the sets of executable code which have been evaluated in the virtual environment and has been validated as “safe” by the system. Accordingly, if a given set of executable code is processed using a hash algorithm and produces a hash output which matches a hash value within the authorized hash database, the system and/or the user may be able to identify the such a set of executable code as being safe to execute or install without the need to re-evaluate the executable code within the virtual environment. In this way, the system may be able to avoid unnecessary duplication of validation processes.

In some embodiments, the authorization database may further comprise hash values of executable code generated by third party computing systems. In this regard, third parties other than the entity may perform the validation process of executable code as described herein to generate hash outputs of the validated (e.g., “safe”) executable code, where the third party may have, for instance, an information-sharing relationship with the entity. In such embodiments, the system may be configured to import hash output values from a third party computing system (e.g., a hash database server owned and/or operated by the third party) and incorporate the hash output values into the authorized hash database. In this way, the system may be able to efficiently control the execution of executable code within its network environment without expending computing resources unnecessarily by retesting the executable code.

In other embodiments, the authorization database may be an unauthorized hash database which may comprise hash values of executable code which has been evaluated within the virtual environment and has been deemed by the system to be unsafe (e.g., the executable code contains malware). In this regard, the system may use the hash values within the unauthorized hash database to positively identify executable code which has been blacklisted by the system. Accordingly, if the hash values of any given set of executable code match those found within the unauthorized hash database, the system may automatically block the installation and/or execution of such executable code.

FIG. 3 illustrates a process flow 300 for validating executable code using an authorization database, in accordance with some embodiments of the present disclosure. The process begins at block 301, where the system receives a request from a user to execute a second set of executable code. In an exemplary embodiment, the system may receive a request to validate the second set of executable code after the authorization database has been generated. Accordingly, the second set of executable code may be, for instance, an installation program that a user wishes to install on a particular target computing system. In some embodiments, the user may attempt to validate the second set of executable code using a dedicated kiosk. In other embodiments, the target computing system may, at least in part, execute the processes as described below.

The process continues to block 302, where the system processes the second set of executable code using the data transformation algorithm to generate a second data transformation output. Continuing the above examples, the system may process the second set of executable code using the same hash algorithm as the one used to generate the hashes within the authorization database. For instance, if the authorization database contains hash values generated using the SHA algorithm, the system may use the same algorithm (i.e., SHA) to process the second set of executable code to generate a second hash output.

The process continues to block 303, where the system compares the second data transformation output to one or more entries in the authorization database. Once the second hash output is generated, the system may compare the value of the second hash output with the values within the authorization database. The authorization database may contain hash values for executable code in the exact state in which the executable code existed at the time of evaluation by the system within the virtual environment. Accordingly, different versions of the same software (e.g., version 1.02 version 1.01 of a productivity application) will have different hash values such that each version of the software is evaluated separately in the virtual environment before being authorized for use and/or installation on the target computing systems.

The process concludes at block 304, where the system validates the second data transformation output based on comparing the second data transformation output with the one or more entries in the authorization database. The authorization database may be an authorized hash database which may contain hash values for sets of executable code that may have been evaluated and deemed by the system to be safe. In such an embodiment, if the hash value for any given set of executable code matches a value found within the authorized hash database, then the set of executable code may be authorized to be installed and/or executed without going through the process of evaluating the executable code within the virtual environment. If a match is not found, the system may determine that the executable code must be validated by the system. Accordingly, in such embodiments, the system may generate a new virtual environment instance and run through the validation process as detailed above.

In other embodiments, the authorization database may be an unauthorized hash database which may contain hash values for executable code which is explicitly unauthorized to be installed or executed by the system. In such embodiments, if the hash value of executable code matches a value found within the unauthorized hash database, the system may automatically block/deny the execution/installation of the executable code. In this way, the system may provide an efficient and secure way to control application installation and usage within the network environment.

Each communication interface described herein generally includes hardware, and, in some instances, software, that enables the computer system, to transport, send, receive, and/or otherwise communicate information to and/or from the communication interface of one or more other systems on the network. For example, the communication interface of the user input system may include a wireless transceiver, modem, server, electrical connection, and/or other electronic device that operatively connects the user input system to another system. The wireless transceiver may include a radio circuit to enable wireless transmission and reception of information.
